cured to each other and so avoid rattling.

It is a further object to provide a clamp which will hold an ornamentalplate in its proper position relative to the bars of the bumper. It isanother object to produce a clamp that will perform the above mentionedfunctions and which will at the same time present a pleasing ornamentalappearance in connection with the rest of the bumper. Further objectswill be apparent from the following description and from the use of thearticles covered by the claims. 7

In the drawings Fig. 1 represents a plan view of a bumper using my clampas a center clamp; Fig. 2 shows a fractional view of the central portionof the bumper shown in. Fig. 1, showing the clamp in detail; Fig. 3shows a sectional view taken on the line 3-3 of Fig. 2; Fig. 4 shows aplan view of the upper front clamp plate shown in Fig. 2. I

In describing my invention I will assume the bumper to which it isapplied to be connected to the front of a vehicle and the'terms' ed atits ends to the ends of the impact bars by means of pins 4, 4 andprojecting forwardly at its central portion for connection to thecentral portion of the impact bars by means of the center clamp to bemore fully described hereinafter.

The numeral 5 denotes an ornamental plate, which may be of grooved steeland suitably shaped to give the desired attractive appearance, adaptedto bear upon the front surface of the rear bar 3. The center clampconsists of a front plate 6, a front plate 7 and a rear plate 10, allheld in position by means of bolts 8 and 9 passing through apertures inthe plates 6, 7 andlO. V

The front plate 6 has a semi-cylindrical lug 11 projecting from its rearsurface and adapted to fit into a suitably shaped aperture 12 in theupper edge of the ornamental plate 5. The plate 6 also has two lugs 13and 14, which are herein shown as L-shaped, projecting from the rearsurface thereof, and which are adapted to pass between the bars and bearat their upper and lower surfaces upon the lower and upper'edges of thebars 1 and 3 respectively. The lower portions 15 and 16 of the lugs 13and 14, respectively, extend rearwardly beyond the rear bar 3 to give anextended bearing thereon and to provide stops to prevent the side motionof the rear clamp plate 10. The plate 6 is adapted to bear at its upperrear surface upon the front surface of the bar 1 and at its lower rearsurface upon the front surface of theplate 5.

The back plate 10 .is bent forwardly at its end portions and so adaptedto hear at its central portion upon the rear surface of the rear bar 3and at its end portions upon the rear surfaces of the impact bars 1 and2.

The front plate 7 is of identical construction with that of plate 6 andsimilar parts thereof have been denoted by reference characters whichare the same as those shown on the plate 6. i

In assembling my center clamp the plate 5 is suitably positioned on thebar 3 and the front plates 6 and 7 are placed so that the lugs 13 and 14pass between the edges of the impact bars 1 and 2 and of the rear bar 3,and so that the lugs 11, 11 coincide with apertures 12, 12 at the upperand lower edges of the plate 5. The bolts 8 and 9 are passed through theapertures 17, 1.7 inthe front plates 6 and 7 and through apertures inthe rear plate 10, which latter plate is positioned between the extendedlugs 15 and 16 so as to bear upon the rear surfaces of the impact andrear bars. By tightening the nuts 18 and 19 the plate 5 is held firmlyin position against the rear bar 3, and the impact and rear bars areheld rigidly in the proper spaced relation. The lugs 15 and .16 preventside movement of'the rear plate 10, the lugs 13 and 14 prevent upwardand downward movement of the plates 6 and 7 or of the bars 1, 2 and 3,and the lugs 11 in the apertures 12 prevent side motion of the plate 5.

The spaced lugs 13 and 14 furnish spaced bearing surfaces between the.edges of the bars and provide a space for the reception of the rearclamp platetogether with a space for the stems of the bolts 8 andv 9connecting the front and rear clamp plates. I

It is apparent that the clamp described above can be used on bumpersdiffering from that herein shown and described, and further,

that it may be used at other points on the of a bumper but it isapparent that it, could be used to'clamp two bars of the bumper and insodoing one of the plates could be omitted.

Having thus described my invention, what I claim is 1. A clamp forholding'vehicle bumper bars in proper spaced relation, said clampincludinga plurality of plates adapted to bear upon the front surfacesof bars of the bumper, each plate having spaced lugs projecting from therearsurface thereof and adapted to fit between the spaced bars and bearupon the adjacent edges thereof, a plate adapted to bear upon the rearsurfaces of said bars and means, for drawing the plates toward eachother.

2. A clamp for holding vehicle bumper bars in properspaced relation,said clamp including aplurality of plates adapted to bear upon frontsurfaces of bars of the bumper, each plate having spaced lugs projectingvfrom the rear surface thereof and adapted to fit between and projectbeyond the rear surfaces'of thebars and to bear upon adjacent,

edges thereof, a plate adapted to fit between the portions ofthe lugsprojecting beyond the bars'and to bear upon rear surfaces of the saidbars, and means for drawing said plates toward each other.

3'. The combination with a pair of bumper bars and a plate adapted tobear upon and be clannied to one of said bars. of means for clampingsaid plate and bars in proper spaced relation, said means including afront clamp plate, adapted to bear upon the front surface of one of thebars and upon the front surface of the clamped plate. means connected tosaid clamp plate for preventing side motionof the clamped plate, a rearclamp plate adapted to bear upon the rear surfacesof said bars and meansfor drawing the said clamp plates toward each other.
